Awesome design! Love the color scheme, and absolutely love how you used the texture on the dark side and used that dark grey instead of a solid black. Very nice.
The only thing I find to be a bit off is the choice of what you capitalized and what remained in lower case or normal case. Like the logo and the word "minus" and then it goes Design Studio. Really like that but then I look at the name ERKAN MALCOK and then graphic designer. This just may be me being picky but I think it would be interesting and more cluid to followe the style you have with your logo. Have the name all lower case and follow that through. It might even be interesting to follow this on the dark side as well. I see you have Creativity in all caps but it being white alone is such a great impact that I am not sure you were need the all caps there.
But I think you have a really great design, love the color scheme and the typography really is great!
I cant think of anything that you would need to change on this.
The red text above and below CREATIVITY seems to a bit blurred or fuzzy....Maybee that is what you were going for but it is just a bit hard to read. Other than that I think you ahave a great design!
Your objective is clean, so to me this has too much detail with the textured black and the watermarked logo.
I'm a bit confused with your logo as a plus when your company is called minus, it's distracting me from everything else - sorry I had to say.
The contrast on the red and black doesn't seem good enough but I am viewing on a 10" laptop screen.
The text on the light side could do with some tweaking not sure what you've done to your contact details but they don't look comfortable like your name and title do.
I would move the web, branding, print and line much nearer to minus, they look like they are floating at the moment and not really belonging.
Sorry this is a bit negative compared to your other reviews, but it is how I see it.
